Crash while running WebCore::SourceBufferPrivate::processMediaSamplesOperation

Reviewed by Youenn Fablet.
It was possible for either memoryPressure or removeCodedFrame to be run in the
middle of a pending appendBuffer operation.
The move to NativePromise already eliminated most of the possibilities by
removeCodedFrame operation wasn't queued to the pending
list of operation.
We now only process removeCodedFrame once we have fully completed any pending
appendBuffer.
Also, we allow for the appendBuffer operation to be aborted in more places.
